Ea
activation energy (amt. of NRG needed to get a reaction going)
-
photosynthesis type of process (catabolic/anabolic, endergonic/exergonic)
- anabolic, endergonic
- consumes energy to build complex molecules from simpler ones
- needs NRG to take place
-
cellular respiration type of process (catabolic/anabolic, endergonic/exergonic)
- catabolic, exergonic
- organic compounds break down into simpler substances
- releases NRG
-
purpose of cellular respiration
to break down hydrogen atoms in glucose to get its energy
